IIVIPROVED PRESSURE-BLOWER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whomtt may concern:

Beit known that I, WILLIAM C. Gnnrns, of the city and county of Philadelphia, and the State of Pennsylvania, have invented a new and improved Pressure.

Blower; and I do hereby declare that the following is a correct and exact description thereof, reference heilig hadio the accompanying drawing, and to the letters of reference marked thereon.

The object of my invention is to obtain a simple rotary pressure-blower for the use of foundries, smitheries, 85e.

The nature of my invention consists in arranging a series of bellows (or chambers formed after the manner of bellows) to revolve around a common centre or anis, with their opposite and inflexible sides attached to two rotative disks or obtuse cones, mounted on the coupled or contiguous ends of separate shafts that lie at an angle of a few degrees, causing the disks to revolve in planes inclined, the one to the other, and the inflexible sides of the bellows to alternately approach and recede l as they revolve.

To enable others to make and use my invention, I will describe more particularly its construct-ion and operation.

` Refer-moes.

Like letters refer to like parts in all the figures.

Figure l, top or plan View of the blower.

Figure 2, end view' of the blower, with the drivingpulleys removed.

Figure 3, vertical longitudinal section of the blower.

Figure 4, front or inner View of the air-receptacle and discharge-pipe.

Figure the series of blowers, with one disk removed.

A A, the frame.

B B, metallic shafts.

C C, series of bloweis.

D D', disks.

E E, semicircular air-chamber.

F, studs to hold the same.

a a, bearings to the metallic shafts.

b b, ball-and-socket joint.

d d, cogged coupling.

e c, apertures indisk D.

f, air-tube.

t' i, set-screws:

l Z, driving-pulleys.

The frame A A is for the support and proper bea-rings of two metallic shafts, B B, that lie at an angle of a few degrees, the one from the other. They are connected, the one to the other', by 'a ball-and-socket joint, or other-formed joint, that will allow of their rotation.

Upon or near the coupled ends of these shafts I firmly aiix two disks, D D. They are made more or less convex upon their inner or contiguous sides. To these disks I attach a series of bellows or flexible chambers, C C, the wooden or inflexible sides of which are bolted or screwed to each disk, while frornthe angle iu the line of the shafts the disks revolve in planes inclined, the one to the other, and canse the opposite sides ofthe bellows to approach and recede as the disks revolve. Thus the bellows are made to act without any oscillating or reciprocating motion.

The air passes into and from the bellows through the apertures e e e in the disk D. From the bellows it passes into the semicircular chamber E, and from thence, by the tube f, to the place required.

To avoid the escape of air from the chamber E while the apertures are coming over the edge or wall of it, f

the latter is made as broad or wide as the diameter of the aperture.

This chamber embraces or covers that part of the circle of apertures from which the air is being expelled,

while the other half is open to the air, no valves being required.

A joint sufficiently tight for all practical purposes is made between the disk D and the air-receptacle E by turning the face of the former to a true plane, and planing or dressing the side of the latter to correspond therewith.

The air-receptacle `is attached to the alne, and adjusted by the set-screws i t'.

The bellows may be leather-ed after the manner of the common hand or smith-bellows, or in the form of the accordeon-bellows. p

For obvious reasons, the disks should retain the same relative position, in the direction of their rotation, the one to the other. This may be done by placing a coupling upon the ends of the shafts, (over the ball and socket,) constructed after the manner of two very obtuse-cog wheels.

What l claim as my invention, and desire to secure by Letters Patent, is-

1. A series of rotative bellows, c c c, in combination with the angled shafts B B, arranged to operate substantially as hereinbefore described, and for the purpose set forth.

2. The arrangement of a series of valveless bellows between two rotative disks or obtuse cones that revolve in planes inclined, the one to the other, as hereinbefore described, and for the puipose set forth.

3. The semicircular air-chamber E, in combination with the disks D D and the bellows C C, arranged to operate as hercinbefore described, and for the purpose set forth. WM. C. GRIMES. Witnesses:
